San Francisco’s prominence as a rock ‘n’ roll town began in the 1960s with the growth of the counterculture movement. Musicians in the area were influenced by Motown and the bands that were part of the British Invasion. Psychedelic rock and jam bands like the Grateful Dead grew in popularity. The Dead, along with Sly and the Family Stone, Janis Joplin and many others made up what became known as the “San Francisco sound.”
